Welcome to the UGRA's presentation of the Guadalupe River corridor films for 2023. The maps and films displayed below were captured and produced in winter and spring 2023. Routes mapped include the North Fork, South Fork, Johnson Creek, and Guadalupe River within Kerr County. To view the videos, follow the link below, and simply choose which years to compare and click on a waypoint on the map. For help, please scroll down below the link for detailed instructions and FAQ.
Click Here for Maps and Videos
This website is a public tool to view the river corridor videos produced by the Upper Guadalupe River Authority (UGRA). Using the link above, you will find a page with two panels -- the top panel is for navigation and the bottom panel is for video players. You can choose to compare two videos, three videos, or four videos, and you can select which years appear in which video panel.
The top panel is a Google Maps applet. If you are familiar with Google Maps, you will find the navigation to be very intuitive. If you are not, don't worry, these instructions will explain how to use the maps below. Each red marker on the map corresponds to a specific point in the videos of the river. Using the map pane, you can zoom in to your area of interest and simply click on a red marker. The marker will turn green, and the appropriate videos will load in the viewer panel and will begin playing. (Don't worry, there is no audio included in the videos, so don't adjust your speakers.)
By default, there are two videos that begin playing simultaneously. The video on the left is the 2023 video, and the video on the right is the 2022 video for comparison purposes. The videos should start playing in sync, but will likely drift apart over time. Simply press the "Sync" button or pause the video that's in the lead for a couple of seconds until the slower video has caught up. The speed that the videos load will be dependent on your internet connection speed and the connection speed to YouTube.
All of the videos are filmed moving downstream. That is, the footage begins upstream and moves downstream -- begins west and moves generally east. Therefore, if you choose one of the red markers, your video will begin at that point and move downstream.
Once a video begins playing, you can use the YouTube player panel to move forward or backward in time, or downstream and upstream, to view your area of interest. If you reach the end of one video timeline, simply select another red dot downstream from the endpoint of the video you just viewed.
All of the videos are filmed in ultra-high definition and can be viewed in up to 4K resolution. To view the high resolution version, simply click on the "gear" icon at the bottom of each YouTube player and select a quality setting. Note that some computers may have issues playing the higher resolution files due to processor speed or internet connection speed.
Using the Navigation Panel (Google Maps)
Google Maps is a very intuitive navigation system on the top panel of this site. When you click and drag inside the panel, you will move around in any direction you choose. When you roll your middle mouse button forward, you will zoom in. Roll the middle button backward to zoom out. Another method of zooming requires you to click the plus or minus icons on the top left of the panel to zoom in or out, respectively. When you zoom in far enough, you will begin to see streets and street names and other features that will help you figure out where you are on the map.
If you would prefer to see a standard road map instead of the satellite imagery, click on the top right portion of the panel on the word "Map" and you will be presented with a simpler road map version.
